I'm a normal engine type, but this is my second set of sports plug cords.
Since the plugs and oils were replaced as a set, this is not a simple parts evaluation, but the engine response is clearly better than before the replacement.
It's a shame that with the RX8, even if you remove the engine cover, the presence of the parts is weak.
I plan to repeat it at the next vehicle inspection.
